Bellhanger Bits

Bellhanger Drill Bit – Product Description

A bellhanger drill bit is a specialized, extra-long drill bit designed for installing wiring through walls, ceilings, and floors with minimal surface damage. Commonly used by electricians and low-voltage installers, it allows for efficient routing of cables such as data, security, phone, and doorbell wiring.

Built from durable high-speed steel or carbide, bellhanger bits feature an aggressive cutting tip that easily drills through wood, metal, drywall, and even light masonry. Their extended length provides superior reach, making them ideal for drilling through multiple studs or hard-to-access spaces.

A key feature is the cross-bored hole near the tip, which allows users to attach wire and pull it back through the drilled hole—eliminating the need for additional tools or steps.
